PROJECT CONSIDERATIONS The project will involve improvements to the Schumann Drive and Barber Street intersection in Indian River County , Florida . The Schumann Drive improvements will begin approximately 1 ,400 feet south of the intersection and extend to approximately 840 feet north of the intersection . The Barber Street improvements will begin approximately 960 feet west of the intersection and extend to approximately 660 feet east of the intersection . Please note that Dunkelberger previously provided geotechnical services for improvements to Schumann Drive south of the intersection as part our Roadway Soil Survey for the 66th Avenue Improvements . The scope of work outlined in this proposal includes supplemental exploration to evaluate an eastward shift to the roadway aligmnent in the 1 ,400 feet immediately south of the intersection . The following items will also be incorporated into the design of the intersection improvements : • Three pond sites are being considered .

A new pond may be constructed on the west side of Schumann Drive, south of the intersection, where the alignment shifts to the east . Another pond may be constructed on County owned lots on the east side of Schumarm Drive approximately 400 feet south of the intersection.
